" To all 'whom ity/may concern:

Be it `known that I=,'DANIEL E. Soms, of

l Washington, in the county of Washington I and in the District ofColumbia, have invented a new and useful ImprovedItefrigerating and`PreservingApparatus; and I do hereby declare that the following is afull, clear, and

. exact description thereof, reference being had `tor-the annexeddrawings, making' part of this .specifica-tion, `in which- Figure 1 is aplan view of my improved refri gerating and preserving apparatus, thehead of the ice=receptacle and portion ofthe upper f wall of thepreservingfbox being removed to.' y show theirinterior; arrangement.Fig.` 2 is a vertical section on line .fr ac of Fig. 1.

My invention relates to a refrigerating and preserving apparatus; and myimprovements 'consist 1n sundry peculiarities of construcfl tlon andarrangement of various parts, as will be more speciiically set forth inthe following 'i specicationand claims. e

' To enable others skilled in the art to make and use my invention, Iwill'proceed to de` scribe its construction and operation.

In the annexed drawings, A represents theV ice-receptacle, andfB thepreservingbox, the

former of which is setinto the latter, having no connection therewith,excepting through valves or cocks A5. Vhen the ice-receptacle projectsabove the top ofthe preserving-box, as I have shown in this instance,such Apro- I valve.

j Vecting part is constructed with multiple walls, the spaces betweenwhich may be filled with air,or some good non-conducting substance, as

charcoal, cotton, tow, and the like. Around the innermost wall 1 preferto construct i'lues, which are always left open for the airto circu latethrough, and may communicate through registers a in the head A1 with theexterior atmosphere. These iiues are marked A2 in i Figgl. A3 is anindependent flue or pipe ex'- tending from. near the top of thepreservingbox upward through the head of the ice-receptacle, beingprovided with a suitable damper.

This pipe is used for introducing fresh air into the ice-receptacle, andmay be used in connection with a cock or valve, A,Figs. 1 andv 4, t'ocool the atmosphere in the room in which this apparatus is placed, warmair constantly ,falling down through the stack to take the place'of coldair discharged through the a single wall, so that its temperature may bereadily transmitted to the latter. Valves or cocks A5 serve to open orclose communica-- tion between the ice-receptacle, and preservV`ing-box. A6 represent diaphragins or grates,

placed at di'erent altitudes in the ice-recep tacle, for the purpose ofsupporting the ice 'or other cooling substances at different heights Vtherein,all the diaphragms being made so that they can be removed out ofthe receptacle.

The preserving-box may be made of any l suitable size and form to suitthe various conditions under whichit is to be used. Allrirtswalls aremade multiple, packed between with good non-conducting substances.

e vAll aroundv the ice receptacle are placed tanks or boxes B1, ofconvenient size and form, and either rigidly secured in thepreservingbox or loosely set into the same,so` that they can be removedtherefrom. In the latter case they are providedwith iianges around theirupper ends, as show n inl the .right-hand section of Fig. 4, suchflanges being provided on their upper and under'surfaces with a con-Vtinuous groove, somewhat fiat, in which rubber tubes or other packingare fastened, for the purpose of making the joints between the flangesand the preserving-box, as well as between such iianges and the doors orlids which That portion of the ice-receptacle within the preserving-boxis constructed with y 2.', lomesn close the tank, air-tight. I prefertoemploy .theserubber tubes in every case where open.: ings are made inany part of the apparatus,

and closed by doors or lids.

The tank-s, whether rigidly connected tothe preserving-box or ysetloosely into the same,

j must always be made water-tight, and no communication must existbetween the two.

In any convenient part' of the preservingbox I propose to insert anice-cream freezer,

' C, consistingof a ,cylinder of suitable size,

made of sheet metal by preference, in which an agitator, ,01, ispivoted, extending some of the cylinder, as

- tending-a short distance through the same to receive .a bevel-wheel,C3, which meshes into and is driven by 'another bevel wheel, C4, mountedupon a horizontal shaft, placed in suitable bearings, and having a crankor other device upon its outer endby which to turn it.

The otice of the box C2 is to receive lumps of ice, ice and salt,` orother cooling substances,

for the purpose of freezing the cream in the cylinder independent oflthe other parts of the apparatus.

The cylinder C is inclosed by an open or lslotted case within thepreserving-box, and i prevented from'turning by anges c' upon itsperiphery, which take into grooves formed in the inclosing-case.

The beaters upon the agitator-spindle are in the form of screws, so thatin turning the 'agitator in one direction theypress the contentstowardthe bottom of the cylinder; but on turning the same in the oppositedirection thy tend to lift the contents out of such cylm er.

. D is another vessel set into the preservingbox, which is to receivewater to cool the same, it Ibeing provided with a discharge-pipe in itslower portion, extending through the' side wall or bottom of thepreserving-box, andprovided with a suitable cock, as showndn Figs. land2. Y .Y

Afaucet is arranged in the bottom of the preserving-box at B2, Fig.`1,by which to draw;

oi any liquids whichit may be desirable to Pipes E and E oxtjomiithrough tho bottom of the ice-'receptacle to different heights,`asshown,through which to discharge the water or other liquidstherein. They are provided with traps and cocks on the outside, thetraps being for the purpose of'preventing the escape of the cold airfrom the ice-receptacle.`

This apparatus may be operated in thefol- -lowing manner: C lhepreserving-box, when af very low temperaturel isl wanted, is filled,

.through suitable openings in its top, with ivater or brine, whichsurrounds the ice-receptacle, tanks, ice-cream freezer, and wzucfcoolerupon all sides. he upper diaphragms or grates-.in the ice-receptacle arethen taken out of the salue, and a suflicie'nt quantity of ice or othercooling substances placed upon the lowest grate. Very soon a very lowtemperature willjbe obtained in the preservingbox, which temperaturesoon reducesv the air in the tanks to the same js'tate. 'Alow'temperature can thus be maintained, with little expense of ice,i11the various ltanks and other devices inserted into the preserving box.Sometimes such a low temperature is not desirable. The brine is thenremoved from the preserving-box, and air' only used. In this instanceythetemperature in the preservingbox can be readily regulated by openingor -closing the cocks in the ice-receptacle. The

lower portion of the ice-receptacle is generally tobe lled with brine,the level-of which can be determined by the discharge-pipes.

. In the application of my invention to preserving-houses andpacking-houses, and the 1ike,the stack or ice-receptacle may extend onestory ormore above the'prcserving'box or chambers or salting-tanks, andbe filled tothe top, thus securing a supply of ice suflicient tolast'several months, or an entire year.'

- When used for cooling buildings or apart ments, and Ventilating thesame, the air, as'it falls through the flues or pipes A? and A3, isconducted through the valve A4 to the different apartments to be cooledby means of tubes provided with valves for regulating the supplythereof.

The chambers or tanks maybe made of any suitable material; but glass,made independ' ently of thei other parts of the apparatus, with groove'dlian ges, as shown in Fig. 6, and placed within the case, is preferable.

Having `thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination of the preserving-box or refrigerating-'c amber,ice-receptacle, and icecream freezer, operating substantially asdescribed.l

2. The combination of the refrigeratin'gchamber, ice-cream freezer,water-cooler, and Ventilating-tubes with an ice-box, substantially asset forth.

, 3. An ice-cream freezer with an ice-box.

forming the cover thereto, substantially as shown and'described.
